Application April 16, 1949, Serial No. 87,961 i (o1. -55) 10 Claims.

This invention relates to a storm sash to be fittedto window in theconventional type of residential building, or similar structure. It isdirccted particularly to a storm sash unit, which may be packed and soldin the conventional type of carton or container, and assembled andinstalled by a home-owner, or other relatively unskilled person, withoutspecial tools and withou requiring a high degree of skill.

`The primary object of my invention is to provide a storm sash unit,which can be assembled and installed, with a minimum of labor, by arelatively unskilled person.

1A further object is to provide a unit, the parts of which are readilyassembled, using relatively simple fastenings, and which can be packedand shipped in a relatively small, compact container.

` vA further object is to provide a storm sash, in

which the major frame members are interchangeable and reversible, sothat the same dies can be used for several of the major parts; p

`A further object is to provide a window sash construction which islight, compact, rigid when installed, readily removable without tools,and will withstand the action of the elements over sustained periods.

V:A further object is to provide a sash construction, which may beeconomically manufactured, sold as a disassembled unit, and assembledand installedrwithout the necessity for highly skilled labor.

. Another Objectis to provide a unit, the parts offwhich can be producedin moderate quantities, in a wide range of sizes, with a minimum ofelaborate and expensive tooling, and still produce parts which areadaptable to a wide range of window,

sizes except for the cut-off length of the frame parts.

. A further object is to provide a unit which is readily adjustable, totake care of inaccuracies in window frame sizes, and buildingdistortion, without additional machine work or special tools.

The accompanying drawings, illustrative oiseveral embodiments-andmodifications of my invention, together with the description of theirconstruction and the method of operation there of, will serve to clarifyfurther objects and advantages of my invention.

Fig. 13 represents a partial plan view of the jamb and a partialvertical section through the sash side member, with the sash xed to thewindow frame.

Y While there are a number of storm sash units available on the market,they are generally relatively expensive to the home-owner, must beaccurately tted to the window frame, and require a considerable lengthof time, on the part of a highly skilled, specialized mechanic toinstall them.

In small communities, particularly those located ata considerabledistance from industrial centers, the overall cost of installing stormwindows, including the cost of the window and sash, the shipping costs,and the installation labor costs, coupled with the added factor thatskilled mechanics, must often be transported over long distances toinstall them, renders the overall cost to the owner extremely high.

The unit, containing all of the necessary frame parts, the hardware andfittings required to assemble them, the necessary hangers, and thematerial for supporting the window glass may be precut to the windowframe size, packed in a compact package, purchased as a kit, andinstalled by the owner.

Asidev from the kit proper, the owner merely purchases the glasssections, precut to size, these sections being readily assembled andtted to the frame sections, without special skills.

The storm window may be installed in such a manner that the sash is xedto the window frame, or ttings may be provided to enable the entire sashto be pivotally opened, and maintained in the open position.

It will Vbe understood that the foregoing general description oftheconstruction and installation of the storm window sash kit, as well asthe following detailed description thereof, are intended as explanatoryof the invention and not restrictive thereof.

In the drawings, the same reference numerals designate the same partsthroughout vthe various views, except where otherwise indicated.

The storm window sash as indicated in Figs. l, 2 and 3 comprises,essentially, a frame I0; made up of two substantially vertical sidemembers, II and I2, anda.topandbottommember, I3 and I 4, with a muntinbar `idioot-meeting the two side members, substantially at the centerthereof.

Two or morecpanes 16.ofswindow-glass, or a transparent plasticmaterial-may be.l mounted in the Vchannelsll and `I8,:fformed -in theframe section and muntin bars-respectivelyfthe numberof windowksections, depending ,upon the number of openings,-or lights ineach'vvindow.

As indicated in Figs. .5.;fr1d'6, a; packing channel 20, formedof ,aflat strip 2I, of rubber or other suitable-materiaL may -be-fltted vintothe channels I'I and I 8,formed i n the A'frame members Aand muntin bar,to effectively-grip the edges ofthe glass sheet,a r 1d to provideaireand watertight joints, around the glass on all sides. The packingchannel 2i), may be furnished molded or otherwise` formedto theUrsetion, indicated in Fi g s. 5 anddinsteadof beingv shaped from a flatstrip.

The section thruthe. veijtizaland horizontal frame members II `23,-nd AIf3, andthe method of supporting thev window panes, areyshown, in detail,in Figs. and 6.

Fig. 5 shows a Y crossfsection1 thru the material of a typicalframe-member. The lower, or window supporting end, is .formed of `aU-shaped section 22, made of extruded aluminum, or a smilar material,witha channel I'al,for med thru the entire length o f the openendofthesection.

The intermediate section 23, and the outer section 24, of the framemember may be formed integral withthe U-shaped'section, vthe entiremember being. extruded or rolled in long lengths, and cut to the lengthrequired fora specific window size.

Vertical and horizontal scribe mouldings or mounting strips 25 and 26,may be adjustably attached to the outer sections yof the vertical andhorizontal frame members, as indicated in Figs; 3 and 4, to Vattach the.window to jamb. These mouldings may be made of thin strips of aluminum,-or another metal orfibre strip.

As indicated in Figs. 5 and 6, Vthe moulding s tripis located at thecenter line of the window channel,with the outer section 24, of theframe member, located at the right-hand side of the moulding in thevertical frame side member when the frame member-section is located inthe right-hand position, .Fig..5.and at the left-hand side of themoulding [when the vframe membersection is reversed toform-thehorizontal crossmember I3, Figs. `3 and 6. Thedistancebetweenthe mounting face 21, of the outer secton-and the. Vcenter-lineSof the .channel isthus held con- 4 stant, regardless of whether thesection is located at the left or right-hand side of the channel, thusassuring complete interchangeability of all of the material sections ofthe frame members except for variations in length.

The reversibility of the frame section material provides greateraccuracy of assembly of the window frame, and sharply reduces thematerial costas only oneV set of extrusiondiesis required for all of theframe mem-bers, regardless of their position, or the size and shap'eofthe window.

`The U-shaped window support sections of the horizontal and verticalframe members are mi- A ,teredjtfas indicated in Figs. 3 and 4, a screwor bolt being tted thru the mating circular or square openings 30 and3I, formed adjacent the :junction between the horizontal and verticalframe member corners. Although Fillister head boltsflare-shown in Fig.2, the holes 30 and 3| may be countersunk, and flat head boltssubstituted therefonftobring the headiofthe bolt vsubstantially` flush-with the `outer surface ofthe frame member section.

In order to provide for; height land width` adjustments, to take care ofdimensional variations and angular distortion inthe window jambdimensions, a-plurality of elongated slots-32 may be formed inthemoulding, the center-line of the slots being in substantial. alignmentwith the openings 3 3, in the outerA section of the corresponding framemember, or similar slots 34 may be formed in the outer section of theframe member, the center-line of the slots being in substantialalignment with a plurality of circular openings 3 5, formed inthemoulding, as indicated in Fig. 4, the .slots providing foradjustment ofthe frame members, inadirection generally perpendicular tothechannelfand: therefore, permitting lateral and slight angularadjustment ofthe window frame members.

The muntin bar I5 may be formed in an H-section, as indicated at thecenter of-Fig. 8. the section comprising two parallel flanges 38 and 39,connected by a central integral webll, thewidth and depth of thechannelsI 8, formed at both sides of the bar, being substantially .the same. asthat of the channel I'I, formed in the frame section,r so that theflanges of the frame section and those of the muntin bar are in.substantial alignment, when assembled, as indicated in Fig. 8. Theflanges of the muntin bar may be cut back for a short distance, and the.ends of the web, notched. at one side,to 'form projections 4I and 42 atboth endsthe width of theprojections being somewhatlessthan the-distance between the inner face ofthe ilange, of 'the' U-shaped sectionof the 'frame member, and the face ofthe intermediate section of theframe member, as indicated in Fig. 8.

In assembling the muntin'bar to the window frame members, each oftheprojections is fitted thru -a'substantially rectangular slot 44, formedin the rear wall of the U-sh'ape'd section vofthe frame-member, vtheouter end Iof the projection being bent, las indica-tedin'lFigQ, towsecure-the webto the frame member.

Figs. l0 and 11 show the adjustable storm sash, as pivotally-attached tothe frame of the window, the sash in Fig. -10,1being.in'thefclosedposition, and that in Fig. l1, in-the open position.

The sash frame I5 may be pivotally supported on the head 45, of thewindowiframe, by means of -ahanger 46, which is attached to the windowable means of attachment.

head by apllllality:.ofscrews'l. or `by other suitthe notchedextension5.2, of the hanger, as indicated in Fig. l0, the curved form of thegroove 53, at the top of the extension, combined with the arcuate shapeof the bottom of the extension, permitting the sash to be angularlyswung from the closed position, shown in Fig. l0, to the open position,Fig. 11, with a minimum of frictional resistance.`

pivoted,V-shaped stay-arm 55 may be mounted between the sash and thewindow frame, to limit the angular movement of the sash frame, andretain it in the desired openposition. The stay-arm comprises two bars56 and 51, of sub stantially rectangular cross-section, the upper endsof the bars being pivotally connected to one another by means of a rivet56, abolt, or other suitable connecting means. One of the bars 56, maybe offset, with the other bar 51, substantially straight, the extent ofthe offset being determined by the form of the window frame members, andthe relative position of the stay-arm mounting brackets on the windowand sash frames respectively.

The lower end of one bar 5l may be pivotally attached'to the verticalside member of the sash frame by means of a screw or pin 59, attached toa bracket 66, which is riveted to the side member, or by other suitablemeans. y A slot 5I may be provided in the lower end of the other sidebar 56, a screw 62, or wing screw, with a washer 63, mounted below thehead thereof, being threadably attached to the vertical member of theWindow frame, to lock the staybzar in position, the slot providing forvertical adjustment of the bar, and consequently angular adjustment ofthe stay-arm, and the storm sash frame in the open position.

The storm sash may be mounted outside the window frame, as indicated inFigs. 16 and 11, or the sash unit, constructed in substantially the,same manner, may be mounted at the inside of theframe, and atta-ched tothe window frame by one of several suitable methods, known to the art. f

, Two methods of attaching the storm sash to the Window frame are shownin Figs. 12 and 13.

In the construction shown in Fig. 12, the sash is tted with one or morestay-arms, as indicated in Figs. `and 11.

One leg of a right-angle bracket 66, may be attached to the intermediatesection 23,` of the frame side member II, by means of a plurality ofrivets 65, or by other suitable attaching means. The lower end of thestay-arm bar 51, may be pivotally attached to the other leg 66 of thebracket, by means of a screw or bolt, 'as indicated in Figs. 10 and 12.The lower end of the other stay-bar 55, may be attached to the side ofthe window jamb frame by a screw 62, as hereinbefore described. Thescribe moulding strips 25 and 26, would be attached to the outer section24 of thefsash frame members, as indicated in Figs. 3 and 4, before thesash is mounted in the window frame. The slots 32 formed in themoulding, or inithe outer sections of the frame member, enable themoulding to `be moved laterally or thru a slight angle, with relation tothe frame members, to take care oi dimensional variations in the windowframe opening and .any slight angularity of the window jamb sections.The face of the moulding engages the side of the window frame member, inorder to seal the window opening, when the sash is in the closedposition, shown in Figs. l0 and l2.

The construction, shown in Fig. 13,'is similar to that of Fig. 12,except that no stay-arm is used, the sash being fixed to the windowframe.

One leg of a right-angle bracket 66, may be attached to the intermediatesection of the frame side member by means of a rivet 65, in the samemanner as that of Fig. 12. The other leg 66 of the bracket may bedirectly attached to the window jamb frame by means of a screw 61, or byother suitable attaching means.

The number of brackets used, and the num-,- ber of screws 67, used toattach the brackets to the window jamb frame, would depend upon the sizeand shape of the sash, and the number of brackets supplied with theframe members.

The scribe moulding strips 25 and 26 would be attached to the outersection 24, of the vertical and horizontal frame members, as indicatedinFigs. 3 and li. When the sash is assembled in the fixed position, theface of the moulding en' gages the side of thewindow jamb frame, to sealthe window opening. The slots 32 and 34 in the cuter section of theframe member, enable the moulding to be moved laterally and angularly,to take up :any variations in the window frames, in the same manner asthat of Fig. 12.

In shipping the sash frame to the home own,- er, the bracket 66 may beriveted, bolted, or otherwise attached to the storm sash frame member,or the bracket may be furnished independently, to be bolted to the framemember, or otherwise mounted, at the time of erection.

After assembling the sash frame, and inserting the window panes, asindicated in Figs. 1 and 6, the owner would insert the sash in theWindow frame. l

Fig. 7 shows lth-e various parts of the sash, knocked down and ready forassembly, `as they are boxed or crated for `shipment to Kthe home owner,prior to nal assembly and installation.A

The side member |I I and the top fram-e member I3, Iare shown, cut tothe length required, with the necessary holes or slots punched ordrilled, ready for assembly. The U-shlaped section 22, of each member,,is cut back at both ends, as indicated in Fig. 7, and the corner, atthe ends of each section bevelled 29, to enable the vertical andhorizontal members to be ljoined without overlap, Ias indicated in Fig.3. The opposite side member I2, .and the bottom member 114, areessentially the same as those shown, except that the sections arereversed as hereinbefore ydescribed. The location of the extrudedsection of the side members, 4with rel-ation to the scribe moulding andthe glass is indicated in Fig. 5, and the dot-dash portion of th-elow-er section of Fig. 6, and that of lthe top and bottom members, asindicated lin the lower section of Fig. 6, an-d the dotdash portion ofthe upper section of Fig. 6, the scribe moulding ybeing located in thesame posiition relative to both members, the channel openings II, toreceive the panes of glass, being in substantial alignment with oneanother.

'The scribe moulding strips 25 and 216 to nt the ver-tical andhorizontal frame members, are furnished to cut to length, and thenecessary holes land slots 32, punched or drilled, orfotherwise cutthruthemouldlngto enable Vthe mouldings torbe readilyassembled to theouter section Aof the verticaland horizontal Ifname members, `andadjusted to lthe required dimension and'position, -Without :anyvadditional cutting or machine" work, 'and without special tools orskills.

The packing channelr 20 is furnished nat, either cut to lthe overalllength required, orpreferably rolled, so that it can be sheared4 to therequired length, to t the lchannels in the trame members and the 'muntinbarrespectively, after assembly. y

' After-forming into'a U-sh'ape, to-iit the'channel, the'eorners may be;notched by theowner, orthe channel strip'rnay 'be notched'atthe points-required, prior ton shipment.

The muntin bar l5 may also be furnished, cut to the required length,with the iilanges at lboth end-s cut away for a shortgdistanee, to f-ormthe Webextensions, the extensions being notched Ito form the projectionsdl and `42, as hereinbefore described, to enable the ymuntin `bar'to be'assembled tothe yframe side members. v

.'The hanger bracket d8 may be furnished with the lower flange t()riveted, 'bolted or otherwise attached Ito the upper frame member I3,'or the 'bracket m-ay be Ifurnished independently, to be bolted to theframe member, lor otherwise mounted, -at the time of erection.

The angle bracket ISD, would be riveted, or otherwise attached to theside-member Il, of the sash frame.

The stay-arm `55A could lbe furnished with lthe upper end of the bars,riveted las indicated in Figs. 'l and Vllnthe owner mounting thelowerend of the bars on the 'window frame and |the sash frame membersrespectively, in the manner :previously described.

The frame members and other features of the .construction may beused instorm sash units sold in `kit form, or may be `factory assembled,erected on thefsite, or fitted and installed in any other suitablemanner to best meet the requirements vof Ia particular' installation.

*Thelsash frame construction'is :suitable for 'Windows-in Ithe usualtype of residential building, lrfor small industrial buildings.

The szeoftne sasnframe, the number of window panes, the location ofthemuntin bar, and numberof bars required vwould depend upon the sizeof"the Window opening, and the judgment of thefsimplierand the home-owner.

While an extruded "frame member of ia yspecial ir'rnand size vissho'vmin Figsj and', this may be'variedconsiderably to suit individuallrequirements.

Where the quantities of las-pecic type, or special ornamental design ofsash frame, doA not warrant the cost of extrusion Kdies or Alendthemselves readily to extrusion, the -frame member sectionmay ybe builtup, the various parts wthereof being-riveted, `Wel-ded, tbrazed, orfastened to one anoth'en'bybther suitable methods known to the .ar-t.

The Lsections may yalso be rolledstfampedor formed by :other suitable`means, vknown to the art, theform of the section being varied *to* suitthe requirements of a particular manufacturing process. e

For smaller units, plastic sections may `be utilized, in jplace of themetal seotions'herein described.

1 Themethodof mounting the window -pan-es'in the frame sections, thepacking used to support the glass inrthe'irame'channels maybe variedconsiderably `to suit special requirements.

The method of supporting 'the sash .in the window jamb,- Whether thesash be fixed 'or adjustable may be altered .considerably to 'suitspecialsizes or individual requirementsor to comply with'the judgment ofthe supplier.

Various ltypes of stay-arm constructiommay be substituted 'for the oneherein described. `The stay-arm may be made readily adjustable, and soconstructed that `the sash may be Vlocked in any position, with relationtothe Window jamb.

Itfvvill, accordingly, be appreciated Lthat the sto-rm 'Wind-ow sashkit, herein described; has'new and useful constructional andvopera/tionalifeavtures, `oli-ering distinct advantages ov-'er existing.types of storm sash. It will, moreover, be understood that `theforegoing description of 'the variousfembodiments and modifications ofthe con struction is illustrative, and that numerous changes c-an bemade therein, `without departing from the @essentials of the inventionwhich is, rather, deiined bythe appended claims.
